I have to ask this question as I cannot seem to be able to put the right words together to get an answer when I search.

I do not know alot about SpamAssassin but I seem to think that (unlike PopFile) it does not accept user input back to help it learn. Then how does it learn and know when its working properly?

I am trying Zimbra out for the first time and I do not know how to test to see if it does what I need in all areas. It seems to do most of what I need but how can I tell if SA is working properly and how do I make it work better from within Zimbra?
